Application filed May 21, 1914. Serial No. 889,942.

To all whom it may concern:

Be itknown that I, ALExANDnRKUczoR, a citizen of the United States, and resident of Cudahy, in the county of Milwaukee and State of Wisconsin, have invented new and useful Improvements in Window-Screens, of which the following a description, reference being had to the accompanyin drawings, which are a part of this specl cation. This invention has for its object to provide a 'window screen which may be drawn as a. shade from a roller to cover the space above the lower sash so that the upper sash may be opened to any desired extent and the entire opening will be covered by the screen.

I Another object of the invention is to rovide a flexiblescreen that may be attac ed to window casings at present in use.

Anotherobject of the invention is to improve upon details of construction of window screens of this type.

With the above and other objects in view the invention consists in the window screen as herein claimed and all equivalents.

Referring to the accompanying drawings in whichrlike characters of reference indicate the same parts in the different views:

Figure 1 is a front view of a window having the window screen of this lnventlon embodied therein; Fig. 2 is a longitudinal sectional viewthereof on the plane of line 22 of Fig. 1; Fig. 3 is a transverse sectional view on the plane of line 33 of Fig. 1; Fig. 4 is a side view of the upper part of the window casing; Fig. 5 is alongitudinal sectional view of a window provided with a .modified form of window screen of this invention as an attachment; Fig. 6 is a front view of the upper portion thereof with parts broken away for clearness of illustration; and, Fig. 7 is a sectional plan view through the spring-compartment; p

In these drawings- 10 indicates a window casing having the upper sash 11 and lower sash -12 suspended therein and counterbalanced by means of weights 13 as usual. The space at the upper end of the window casing is boxed in to constitute a roller compartment and the strip forming the inner wall of each weight compartment extends into this roller compartment and is provided with an open notch 14 at its upper end to form an open bearing for a screen roller 15 which has a flexible wire screen fabric 16 wound thereon. The roller. 15 is reduced in diameter at the ends where it .restsin the open bearlngs 14 and has shoulders 17 at .itsextremities, and on the reduced end beyond the bearings 14 is wound a cord or rope 18 in the opposite direction to the di-v rection in which the screen 16 is wound. After coiling around the reduced end of the screen roller 15 the cord or rope passes around a guide pulley 19, which is best shown in Fig.4, so as to be out of the way of the sash weights and then connects with acoil spring 20 which is fastened Within the weight casing at 21 in any suitable manner. This spr ng means for giving the roller its turning movement for windin up the screen may be provided'at one en only of the screen roller, but it is preferred to provide the same at both ends.

- The lower edge of the screen fabric 16 is guide strip which will bear against the front face of the lower sash when it is raised. The-flange of the angle iron strip 24 being spaced from the cut awayportion of the Patented Jan. in, 1915 guide strip 23 provides the slot or groove for the end of the metal strip 22 on the lower end of the screen. These slots or grooves also receive the side edges ofthe screen when the screen is drawn down as shown in Fig. 1. The metal strip 22has an outwardly extending flange 25 to bear upon the top of the lower sash. Suitable means may be provided for drawing the screen and for looking it in its drawn position, such as a cord 26 secured to the metal strip 22 and passing around a cam locking grooved pulley 27 of ordinary construction secured to the window sill.

-With a window screenconstructed in accordance with this invention the upper sash may be opened partially or entirely without admitting flies, it being only necessary to pull upon the cord 26 so as to draw the screen to its lower position into engagement with the lower sash after the upper sash has been opened as desired, and such screen effectively closes all of the.opening. When the screen is not desired it is released and the springs 20 turn the roller so as to draw the screen upwardly until the flange 25 engages the bottom of the roller casing. Should it be desired to remove the screen roller for any reason the front panel 28 of the roller casing may be removed and by detaching the metal strip 22 so that the end of the wire screen passes through the slot in the bottom of the roller casing the roller may be lifted out of its open bearings.

In adapting the window screen of this invention for windows in present use the roller casing is in the form of a box-like casing 29 removably attached to the inside of the window casing by means of pins or tongues 30 projecting downwardly from the rear wall of the casing 29 and engaging cleats 31 secured to the face of the window casing. The screen roller 32 is journaled in the end walls of the casing 29 with the screen 33 wound thereon and passing through a slot in the bottom of the casing. A partition 34 divides the casing 29 into two compartments, the lower compartment for the screen roller and the upper compartment for springs. In the upper compartment coil springs 35 are attached to the ends of the casing and connect with cords 36 which pass around pulleys 37 at the other ends of the spring casing and then are wound about the reduced spool-like portions at the ends of the screen roller. The lower part of the casing 29 is connected by hinges 38 to the upper part along the line of the partition 34 so as to be capable of swinging outwardly, as shown by dotted lines in Fig. 5, and to permit access to the screen roller compartment while the front plate 39 of the spring compartment is removable to permit access thereto. In this form of the invention the guide for the metal strip 40 at the lower end of the screen is in the form of metal strips 41, U- shaped in cross section, secured to the sides of the window casing, and the screen is controlled by means of a cord 42 passing screen is in the form of metal strips 41,

U-shaped in cross section, secured to the sides of the window casing, and the screen is controlled by means of a cord 42 passing over the cam locking pulley 43, as before. The flange of the metal strip 40 engages a strip 44 carried-by the upper edge of the lower sash to complete the sealing fit between the screen and the lower sash. With this form of the invention the operation and effect is the same as with the other form and when the screen is not desired the entire device may be readily removed by releasing the casing from its cleat connection with the window casing and by removing the guide strips 41 if desired.

What ll claim as new and desire to secure by Letters Patent is:

1. A window screen, comprising-a roller casing, a roller mounted to turn therein, a screen wound upon the roller, a cord wound upon the roller in the opposite direction to the winding of the screen, a spring connected with the cord for turning the roller to wind the screen, a strip secured to the end of the screen, guides in which the ends of the strip and the edges of the screen travel, a cord connected with the strip for unreeling the screen, means for engaging the cord, and a flange on the strip for engaging the upper end of a lower window sash.

2. A window screen, comprising a roller casing, a roller mounted to turn therein, a screen wound upon the roller, a cord wound upon the roller in the opposite direction to the winding of the screen, a spring connected with the cord, a strip secured to the end of the screen, guides in which the end of the strip and the edges of the screen travel, and a flange on the strip for engaging a window sash.

3. A window screen, comprising a roller casing, means for detachably connecting the roller casing to the interior of a window casing, a roller journaled within the roller casing, a semen wound upon the roller, a strip secured to the end of the screen, guides in which the ends ofthe strip and the edges of the screen travel, cords secured to the ends of the roller and wound thereon in a direction opposite the direction of winding of the screen, pulleys in the roller casing around which the cords pass, and springs secured within the roller casing and connected with the cords.

In testimony whereof, ll afix my signature, in presence of two witnesses,

ALEXANDER KUGZQR.
